}

And add that anywhere in your script

pawn Код:

stock AddLog(const string[], const logfile[])
{
    new str[150],
        day, month, year,
        hour, minute, second
    ;
    getdate(year, month, day);
    gettime(hour, minute, second);

    format(str, 150, "[%02d-%02d-%04d %02d:%02d:%02d] %s\r\n", day, month, year, hour, minute, second, string);
    WriteInFile(str, logfile);
    return 1;
}

pawn Код:

public OnPlayerRequestClass(playerid, classid)
{
    new string[126];
    format(string,sizeof(string),"You are banned from playeing in server reason : %s",pBannedReason);
    if(PlayerInfo[playerid][pBan] == 1) return ShowPlayerDialog(playerid,23333,DIALOG_STYLE_MSGBOX,"Banned",string,"ok","");
    return 1;
}

Ps: didn't test that but should work
